Method and Apparatus for Disambiguating Probe Points Within an Ambiguous Probe Region

3. A method according to claim 1 wherein identifying an ambiguous probe region further comprises identifying an instance in which a road center shifts by at least a predetermined amount.

4. A method according to claim 1 wherein classifying the probe trajectory IDs from the third set as being associated with the first branch comprises excluding probe trajectory IDs from the third set from being associated with the first branch in an instance in which the probe trajectory IDs are also included in the second set.

5. A method according to claim 1 wherein classifying the probe trajectory IDs from the third set as being associated with the second branch comprises excluding probe trajectory IDs from the third set from being associated with the second branch in an instance in which the probe trajectory IDs are also included in the first set.

6. A method according to claim 1 wherein separately identifying probe trajectory IDs of the probe points along at least a portion of the first and second branches comprises separately identifying probe trajectory IDs of the probe points along a same predefined length of the first and second branches downstream of the ambiguous probe region.

7. A method according to claim 1 wherein the first branch splits into at least two sub-branches, and wherein separately identifying probe trajectory IDs of the probe points along at least a portion of the first and second branches comprises identifying probe trajectory IDs of the probe points along at least a portion of the at least two sub-branches of the first branch and including the probe trajectory IDs along at least a portion of the at least two sub-branches in the first set of probe trajectory IDs.

10. An apparatus according to claim 8 wherein the at least one memory and stored computer program code are configured, with the at least one processor, to further cause the apparatus to identify an ambiguous probe region by identifying an instance in which a road center shifts by at least a predetermined amount.

11. An apparatus according to claim 8 wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to classify the probe trajectory IDs from the third set as being associated with the first branch by excluding probe trajectory IDs from the third set from being associated with the first branch in an instance in which the probe trajectory IDs are also included in the second set.

12. An apparatus according to claim 8 wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to classify the probe trajectory IDs from the third set as being associated with the second branch by excluding probe trajectory IDs from the third set from being associated with the second branch in an instance in which the probe trajectory IDs are also included in the first set.

13. An apparatus according to claim 8 wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to separately identify probe trajectory IDs of the probe points along at least a portion of the first and second branches by separately identifying probe trajectory IDs of the probe points along a same predefined length of the first and second branches downstream of the ambiguous probe region.

14. An apparatus according to claim 8 wherein the first branch splits into at least two sub-branches, and wherein the at least one memory and stored computer program code are configured, with the at least one processor, to cause the apparatus to separately identify probe trajectory IDs of the probe points along at least a portion of the first and second branches by identifying probe trajectory IDs of the probe points along at least a portion of the at least two sub-branches of the first branch and including the probe trajectory IDs along at least a portion of the at least two sub-branches in the first set of probe trajectory IDs.

17. A computer program product according to claim 15 wherein the computer-readable program instructions are further configured to identify an ambiguous probe region by identifying an instance in which a road center shifts by at least a predetermined amount.

18. A computer program product according to claim 15, wherein the computer-readable program instructions further comprise program instructions configured to identify an ambiguous probe region by identifying an instance in which a road center shifts by at least a predetermined amount.

19. A computer program product according to claim 15, wherein the computer-readable program instructions further comprise program instructions configured to classify the probe trajectory IDs from the third set as being associated with the first branch by excluding probe trajectory IDs from the third set from being associated with the first branch in an instance in which the probe trajectory IDs are also included in the second set.

20. A computer program product according to claim 15, wherein the computer-readable program instructions further comprise program instructions configured to classify the probe trajectory IDs from the third set as being associated with the second branch by excluding probe trajectory IDs from the third set from being associated with the second branch in an instance in which the probe trajectory IDs are also included in the first set.
